Final answer:
The statement that an advantage of JIT cross-trained workers is they can help other workers when bottlenecks occur is True. Cross-trained workers are versatile, able to support multiple tasks when necessary, producing efficiency and reducing downtimes in the production process. The correct option is a.
Step-by-step explanation:
The question addresses an aspect of Just-In-Time (JIT) inventory management system, particularly how cross-trained workers contribute to improving the efficiency in a production process. JIT is a strategy which aligns raw-material orders from suppliers directly with production schedules.
In this context, cross-training of workers is beneficial because it equips them with skills to perform multiple tasks. An advantage of JIT cross-trained workers is that they can help other workers when bottlenecks occur, which is True.
Cross-trained workers are versatile and adaptable which allows them to move to different stations or roles within the production process to alleviate bottlenecks or delays, thereby maintaining workflow and reducing downtime. This multitasking ability leads to higher productivity and flexibility in the manufacturing process.
Specialized workers may produce at higher quality and faster speeds, but they might not have the versatility to tackle different tasks, which is where cross-trained workers become an asset in a JIT system. The correct option is a.
